PrimeKG Pathfinding Algorithm Benchmark Laboratory

Benchmarking Graph Algorithms for Drug Repurposing Discovery

Ground Truth Curation

We integrated DrugMechDB with PrimeKG through a structured entity-mapping pipeline to create a benchmark-ready set of mechanistic pathways.

Quality Score

How much of the predicted pathway matches the mappable ground-truth mechanism.

Coverage Score

How much of the full original mechanism is recoverable inside PrimeKG.

Why it matters

These scores separate algorithmic failure from graph incompleteness and ontology mismatch.
